Phone Samsung s5 omega rom with rom toolbox pro

Hi,
Basically I'm very new to rom and rooting. I've just rooted my device and put on omega rom. All good but now I don't know what to do.

What I'm mostly interested in is playing around with rom toolbox pro - cpu control and kernel tweaks. Just looking for your personal choice on what you've adjusted and what works best for you.

I don't want to push my phone and I care about battery life as I'm a heavy phone user so looking for the perfect balance between performance and battery. I assume this is the best app for it? Just really need your recommended settings and specific changes please.
